Definitions

  • the present invention relates to a closed injection moulded closure according to the precharacterizing clause of independent Patent claim 1.
  • the prior art discloses various plastics closures having snap-on hinges.
  • closure part is so close to the pouring opening that it blocks the opening visually. From the point of view of injection moulding, these closures are not without problems. Asymmetrical flow paths, an unfavourable arrangement of the film hinges and cooling problems are only a few of the problems. Owing to the system itself, these disadvantages cannot be overcome. In particular, the main hinge connections between the closure parts, which force the closure parts to form a rotational movement and limit the kinematics of closure are troublesome and particularly disadvantageous.
  • EP 0 532 471 describes a closure which has the disadvantages described above.
  • the lower closure part is connected to the movable upper closure part by means of a main hinge connection and two laterally arranged tension bands.
  • the hinge connections and the tension bands must be arranged in such a way that they are on the one hand capable of being removed from the mould and are accessible from both sides (outside and inside).
  • the unavoidable main hinge connection results in the closure parts having to be arranged very close together, with the correspondingly adverse effect on the opened state.
  • the accessibility of the hinge region which is essential for production, moreover means that the tension bands cannot be designed in any desired manner and the angle between open and closed positions remains in the region of 80° or less.
  • the upper closure part in the open position is in a poor, unstable and random arrangement relative to the spout.
  • An insufficient snap-on effect and the absolutely unfavourable position of the upper closure part relative to the lower closure part in the opened position are obstacles to effective operation. Problems with the flow paths and poor design during moulding are further weaknesses.
  • the main hinge connection moreover results in the closure parts moving along circular paths and therefore being subject to considerable restrictions with regard to the spatial arrangement.
  • the invention disclosed here avoids in advance the bottlenecks to which constructions according to the prior art are subject, by deliberately avoiding a main hinge connection between the closure parts.
  • the movable closure part is positioned outside the zone of the spout or opening. Consequently, soiling of the movable closure part by the contents and visual and functional blocking are prevented.
  • the snap-on effect is established and predetermined in a specific manner in line with the requirements. Owing to the absence of a main hinge, it is also possible for the first time to realize substantially symmetrical flow paths in the hinge region in the case of closed injection moulded closures. As a result of this, problems such as material backflow and cold welds do not occur.
  • connection lacks a main hinge, it is furthermore achieved that the closure parts no longer move along circular paths relative to one another.
  • the spatial trajectories instead correspond to adjustable movement paths which are adapted to the respective requirements.
  • High spouts and other obstacles are overcome in a specific manner.
  • the invention envisages that closed injection moulded closures can be produced with avoidance of the known disadvantages, with or without original warranty seals and with a good design. If desired in a specific case, child-proof properties and security during transport as well as particular sealing in the case of contents with gas pressure can be provided.
  • FIG. 1 schematically shows a closure according to the prior art
  • FIG. 2 schematically shows a closure according to; the invention disclosed here;
  • FIG. 3 shows a preferred embodiment of a closure according to the invention
  • FIG. 4 shows a closure according to FIG. 3 , in the open position
  • FIG. 5 shows a closed injection moulded closure with hinge connection arranged at the top.
  • FIG. 1 shows a schematic side view of a closed injection moulded closure 1 , as known from the prior art.
  • a lower closure part 2 and a movable upper closure part 3 can be seen.
  • the upper closure part 3 is connected to the lower closure part 2 by means of a conventional snap-on hinge 4 .
  • the snap-on hinge 4 consists of a main hinge connection 5 and two tension bands 6 . 1 and 6 . 2 (because of the direction of view, only the tension band 6 . 1 is visible here) which each connect the lower closure part 2 to the upper closure part 3 and as a rule are arranged by the side of the main hinge connection 5 .
  • tension bands 6 . 1 , 6 instead of tension bands 6 .
  • the main hinge connection 5 forms a direct hinge connection with only one hinge axis between the lower closure part 2 and the upper closure part 3 .
  • This hinge axis of the main hinge connection 5 is parallel to the direction of view in the representation shown here. Owing to the main hinge connection 5 having a hinge axis, all parts rotate relative to one another along circular paths.
  • closure parts 2 and 3 must be arranged in such a way that they are accessible in the injection mould (not shown) from the inside of the closure (arrow 10 ) and from the outside of the closure (arrow 11 ).
  • the main hinge is difficult to form.
  • a typical open position of the upper closure part 3 is represented by an upper closure part 7 .
  • the open position of the tension bands 6 is represented by tension bands 8 . 1 , 8 . 2 (only one can be seen).
  • the closure 1 shown here has a small opening angle of about 80° and a poor snap-on effect.
  • FIG. 2 schematically shows a closed injection moulded closure 20 according to the invention disclosed here.
  • the closure 20 consists of a lower closure part 21 and an upper closure part 22 , which is shown here in the closed position in which it is also produced.
  • the closure 20 shown here has (in contrast to the prior art) no main hinge connection (see FIG. 1 ) between the closure parts 21 and 22 .
  • the closure parts 21 and 22 are instead actively connected to one another by two, preferably symmetrically formed, connecting elements 23 . 1 and 23 . 2 (owing to the direction of view, only one connecting element 23 . 1 is visible) and four hinge connections 24 . 1 , 24 . 2 , 25 . 1 and 25 . 2 .
  • the two connecting elements 23 . 1 and 23 are provided to the closure parts 21 and 22 .
  • first hinge connections 25 . 1 and 25 . 2 are connected to the upper closure part 22 through first hinge connections 25 . 1 and 25 . 2 and to the lower closure part 21 through second hinge connections 24 . 1 and 24 . 2 .
  • the first hinge connection and the second hinge connection make an angle ⁇ with each other.
  • Two planes defined by the two pairs of hinge connections 24 . 1 and 25 . 1 , and 24 . 2 and 25 . 2 , respectively (not shown) in turn make an angle ⁇
  • the snap-on effect and an opening angle ⁇ of the closure are determined.
  • the connecting elements 23 . 1 and 23 . 2 and the hinge connections 24 . 1 , 24 . 2 , 25 . 1 and 25 . 2 are arranged in such a way that they are accessible in the mould from the inside of the closure (arrow 27 ) and from the outside of the closure (arrow 28 ) and can be removed from the mould.
  • the connecting elements 23 . 1 , 23 . 2 and the associated hinge connections are arranged in a surface which is inclined relative to the closure axis “A”.
  • hinges according to the patents EP 0 746 512, PCT/EP96/2780 or the Patent application PCT/1999/00277 of the same Applicant are used for the closure, the contents of which are hereby incorporated by reference with regard to the details of the design of the hinges.
  • the hinge according to PCT/EP96/2780 is advantageous since the elastic strain of the longer free edges 46 . 1 and 46 . 2 . (See FIG. 3 ) under tension has the desired snap-on effect.
  • a typical open position of the upper closure part 22 is represented by the dotted line in FIG. 2 .
  • the predetermined opening angle is preferably in the range from 150° to 180° but may also be adapted to other requirements.
  • FIG. 3 shows an embodiment of a closure 20 according to the invention in a perspective view.
  • a lower closure part 21 and an upper closure part 22 can be seen. These are connected to one another by means of two connecting elements 23 . 1 and 23 . 2 and four hinge connections 24 . 1 , 24 . 2 and 25 . 1 , 25 . 2 .
  • the two pairs of hinge connections 24 . 1 and 25 . 1 , and 24 . 2 and 25 . 2 respectively, define a first plane 31 and a second plane 32 , respectively, and make an angle ⁇ , with each other.
  • Shorter free edges 45 . 1 and 45 . 2 closer to the apex of the angle are preferably substantially pressure-resistant.
  • the planes 31 and 32 in turn make a solid angle ⁇ with one another.
  • the planes 31 and 32 are inclined relative to the closure axis “A” in such a way that they are further away from the closure axis “A” in the region of the lower connection (lower closure part 21 ) than in the region of the upper connection (upper closure part 22 ). This permits demouldability of the closure while also making it possible to form the desired hinge.
  • the connecting elements 23 . 1 , 23 . 2 are integrated into a convex outer contour of the closure, with an included angle ⁇ of less than 180° between the planes 31 and 32 . In other embodiments having a concave outer contour, an included angle ⁇ of greater than 180° is enclosed between the two planes 31 , 32 .
  • the hinge connections 24 . 1 , 24 . 2 and 25 are examples of the hinge connections 24 . 1 , 24 . 2 and 25 .
  • the closure 20 is preferably produced by means of injection moulding.
  • the closure parts 21 , 22 and the connecting elements 23 . 1 , 23 . 2 and the hinge connections 24 . 1 , 24 . 2 , 25 . 1 , 25 . 2 are functionally separated from one another here by intervening gaps 33 to 38 so that the movable upper closure part 22 can assume at least two spatially defined and stable positions relative to the lower closure part 21 . There are unstable states (dead points) between these stable positions so that the upper closure part 22 automatically attempts to achieve the nearest stable position and hence has a snap-on effect.
  • the closure parts 21 , 22 , the connecting elements 23 . 1 , 23 . 2 , the hinge connections 24 . 1 , 24 . 2 , 25 . 1 , 25 . 2 are in substantially stress free states (geometric deformations).
  • non-stress-free stable positions are also possible.
  • the connecting elements 23 . 1 and 23 . 2 and the hinge connections 24 . 1 , 24 . 2 , 2 S. 1 , 25 . 2 are typically under a torsional stress and the secondary stresses caused thereby.
  • the connecting elements 23 . 1 and 23 . 2 are formed along a shorter free edge 45 . 1 or 45 .
  • the longer free edges 46 . 1 and 46 . 2 are preferably designed in such a way that they lengthen elastically and reversibly under the tensile stresses occurring. This can be achieved, for example, by a three-dimensional curvature or specific choice of material.
  • the closure parts 21 and 22 advantageously have a certain elasticity so that, if required, they undergo reversible elastic deformation under the loads occurring.
  • the connecting elements 23 . 1 and 23 . 2 are advantageously formed in such a way that they deform in a controlled manner owing to the torsional forces occurring.
  • the coordination between the closure parts 21 and 22 is adjustable through the torsional rigidity of the connecting elements 23 . 1 , 23 . 2 .
  • the desired snap-on effect can thus be achieved by the closure parts or by the connecting elements individually or in combination with one another. Owing to the low torsional rigidity of the connecting elements 23 . 1 and 23 . 2 , it is possible to achieve intermediate states in which the closure parts are stable relative to one another but do not assume tension-free positions. Closures having a plurality of open positions can thus be realized.
  • the closure parts are separated from one another by the gaps 33 to 38 so that the closure 20 can be opened and closed.
  • the gaps 33 to 38 are formed in such a way that they are optimally accessible in the mould and can be removed from the mould.
  • Coupling elements 39 are present in the gap 33 of the embodiment shown here.
  • the coupling elements additionally connect the closure parts 21 and 22 .
  • the coupling elements 39 are designed in such a way that, if required, they serve as predetermined breaking points between lower closure part 21 and upper closure part 22 which are destroyed when the closure is first opened.
  • the coupling elements 39 may also be in the form of all-round, membrane-like predetermined breaking points which enclose one or more desired sectors. A consumer can thus recognize whether the closure has already been opened before purchase (original warranty seal).
  • the coupling elements 39 also serve for preventing unintentional opening during transport, since a greater force has to be overcome on opening for the first time.
  • the coupling elements 39 also serve as flow aids in the production of the closure 20 , in order to achieve better filling of the mould.
  • other equivalent means are also possible, for example in the form of tearoff lips, which have to be removed before opening for the first time, for example by tearing off Integrations of further functions are not hindered.
  • the course of the gaps 33 to 38 can be substantially freely chosen provided that there is no impairment of the mode of operation of the closure and the producibility.
  • the connecting elements 23 . 1 and 23 . 2 are adapted to the outer contour of the closure and are integrated therein. Of course, they may also have another design or may be flat. If required, they may have a connection to one another.
  • An advantageous connection can be realized, for example, in the form of a further (straight) hinged connection, in the form of a film hinge in the case of plastics.
  • FIG. 4 shows the closure 20 according to FIG. 3 in the opened position, in a perspective sectional view.
  • the closure 20 is pressed onto a bottle 50 and thereby fastened.
  • the upper closure part 22 is present in a stable open position swivelled 180° backwards so that a pouring opening 51 for pouring out the content contained in the bottle 50 is unobstructed.
  • the upper closure part 22 is present in an oblique position above the lower closure part 21 so that it does not hinder pouring and the spout 51 is visually not concealed. Because the main hinge connection has been avoided according to the invention and owing to the length of the connecting elements 23 . 1 , 23 .
  • brace 52 for partial stiffening of the closure parts are present on the closure parts 21 , 22 , 23 . 1 , 23 . 2 .
  • the snap-on behaviour and the functionality of the closure 20 are thus influenced in a controlled manner.
  • Brace 52 for stiffening the closure parts are preferably constructed as a rib, thicker region or other equivalent structural element.
  • a tubular element 53 which in this case has an edge 55 thickened with a bead 54 is evident in the interior of the upper closure part 22 .
  • the tubular element 53 or the bead 54 corresponds, in a closed position of the closure 20 , to the spout 51 of the bottle 50 or of an adapter between bottle and closure so that bottle 50 is sealed.
  • the tubular element 53 , the bead 54 and the spout 51 actively connected to them in the closed position of the closure 20 are advantageously designed in such a way that the sealing effect is adjusted proportionally to the internal pressure of the bottle 50 .
  • edge 55 or the bead 54 expands proportionally to the internal pressure and to a greater extent than the increase in the diameter of the spout 51 . Consequently, the edge 55 is pressed to a greater extent against the inner wall 56 of the spout 51 with increasing internal pressure, with the result that the scaling effect is enhanced.
  • a catch 57 is present on the inside of the upper closure part 22 .
  • this catch 57 has an active connection to a counter-element, in this case an outer edge 58 of the bottle 50 , by virtue of the fact that it grips under counter-element 58 and thus prevents unintentional opening of the closure 20 , for example during transportation or in the case of high internal pressures.
  • This locking mechanism can be temporarily released here by lateral pressure on the upper closure part 22 in the direction of the arrows 59 and 60 .
  • the upper closure part is deformed in such a way that the catch 57 moves in the direction of an arrow 61 and the active connection with the outer edge 58 is temporarily broken.
  • the closure 20 can thus be opened.
  • the locking mechanism shown here is also particularly suitable for combination with a quality seal or original warranty seal in the form of a tearoff lip (not shown).

  • the closure comprises a first, fixed closure part 62 and a second, movable closure part 63 .
  • the container 12 may have, in the region of its upper end 67 , a complete opening which substantially extends over its total cross-section, or, in the region of the movable closure part 63 , by a smaller opening which appears as soon as the movable closure part 63 opens.
  • Arranged in the region of the transition 68 between the two closure parts are two connecting elements 23 . 1 , 23 . 2 , which form the hinge connection between the two closure parts.
  • the connecting elements are arranged not by the side of the closure in an inclined surface but on the top of the closure (relative to the closure axis “A”).
  • the geometry of the two connecting elements 23 . 1 , 23 . 2 is preferably designed so that the movable closure part performs a snap-on movement of about 90° or 180°, the formula mentioned above in association with FIG. 2 being used to obtain the desired opening angle a.
  • the avoidance, according to the invention, of a main hinge in combination with the mutual arrangement of the closure parts permits such a closure having a large opening angle ⁇ ), as illustrated in FIG. 2 .
  • the external geometry of the closure can have a convex shape, as shown here.
  • closures in which the connecting elements are arranged in a depression or in which the external geometry is substantially concave can also be realized.
